Physical properties
Bright silvery metallic luster with an irregular, jagged form. Mohs hardness 2.5–3; cubic crystal system, though native silver commonly occurs as irregular masses or wires. The image is too small to confirm composition.
Formation & geological history
Native silver forms in hydrothermal veins and by secondary enrichment in silver-bearing ore deposits; its age depends on the host deposit.
Uses & applications
Silver is used in jewelry, coins, electronics, and industrial applications; attractive natural specimens are collected.
Geological facts
Silver is highly malleable and ductile, and tarnishes through reaction with sulfur compounds in air.
Field identification & locations
A silvery metallic appearance is suggestive but not diagnostic; native silver is soft and can be cut, while many look-alikes are brittle. Common sources include Mexico, Peru, and the United States.
